Stage M1

High temperature superconductors probed by NMR

In this Master project, we propose to perform nuclear Stage M1 - M2 magnetic resonance measurements in a high Tc cuprate superconductor in order to understand the competition between superconductivity and magnetic or charge ordering. The internship will take place in a team of several researchers and will offer a wide range of opportunities: handling of cryogenic fluids and magnetic fields, NMR measurements, data analysis.

Ultrasound in quantum materials

Superconducting materials enable technologies that would otherwise be unfeasible or impossible, such as medical Magnetic Resonance Image scanners, magnetic confinement in the ITER fusion reactor, and the magnets directing charged particles at the CERN accelerators. The materials class with the best current prospects for superconducting applications are the cuprates, which hold the record for highest ambient pressure transition temperature (Tc)-about 150 K. Those materials also host one of the greatest enigma of modern physics: the pseudogap phase. Determining the nature and origin of this mysterious phase is key to understand the mechanism of high-Tc superconductivity.

Stage M2

NMR investigation of low dimensional q uantum spin systems

Quantum spin systems are insulating crystals containing regular array of atoms carrying spin S = 1/2 or 1, described by simple spin Hamiltonians. In low-dimensional model compounds, we study by Nuclear Magnetic Resonance (NMR), which is a microscopic probe to magnetism, the magnetic-field-induced "exotic" phases, such as the Bose-Einstein condensate, magnetization plateaus or spin-nematic phase.

Superconducting nematic phases under stress

Stage M1 - M2 The proposed work consists in setting up a uniaxial pressure device, coupled to NMR measurements (a spectroscopic method whose principle is analogous to medical MRI), in order to study novel electronic phenomena in high temperature superconductors. This Master internship will take place in a team of several researchers and will offer a wide range of opportunities: tests and implementation of the pressure device, handling of cryogenic fluids and magnetic fields, NMR measurements, data analysis

Thermodynamic investigations of the Quantum Critical Point in CeRh(1-x)Ir x In 5

In the series of CeRh(1-x)IrxIn5 at zero magnetic field, the antiferromagnetic order is suppressed at the Quantum Critical Point corresponding to x c = 0.6, while superconductivity emerges above x ~ 0.3. The objective is to investigate the interplay of different types of magnetic orders and superconductivity under ma gnetic field by means of specific heat measurements down to the lowest temperature (~300 mK) for various values of x.

Tuning the van der Waals gap of layered materials with high pressures

We propose to use a diamond anvil cell to apply high pressure on a layered material or heterostructure to finely tune the interlayer distance and all the electronic/magnetic properties that are directly related to this par a mater. Pre s sure induced changes will be probed at cryogenic temperature with opti cal techniques (photoluminescence, Raman scattering, reflectivity) Detailed
